      crypto: atmel-sha - fix context switches · 7cee3508
      Cyrille Pitchen authored
      
      
      This patch saves the value of the internal hash register at the end of an
      'update' operation then restores this value before starting the next
      'update'. This way the driver can now properly handle context switches.
      
      WARNING: only hardware versions from sama5d4x and later provide the
      needed interface to update the internal hash value. Especially, sama5d3x
      cannot implement this feature so context switches are still broken.

      crypto: atmel-sha - fix a race between the 'done' tasklet and the crypto client · f56809c3
      Cyrille Pitchen authored
      
      
      The 'done' tasklet handler used to check the 'BUSY' flag to either
      finalize the processing of a crypto request which had just completed or
      manage the crypto queue to start the next crypto request.
      
      On request R1 completion, the driver calls atmel_sha_finish_req(), which:
      1 - clears the 'BUSY' flag since the hardware is no longer used and is
          ready again to process new crypto requests.
      2 - notifies the above layer (the client) about the completion of the
          asynchronous crypto request R1 by calling its base.complete()
          callback.
      3 - schedules the 'done' task to check the crypto queue and start to
          process the next crypto request (the 'BUSY' flag is supposed to be
          cleared at that moment) if such a pending request exists.
      
      However step 2 might wake the client up so it can now ask our driver to
      process a new crypto request R2. This request is enqueued by calling the
      atmel_sha_handle_queue() function, which sets the 'BUSY' flags then
      starts to process R2.
      
      If the 'done' tasklet, scheduled by step 3, runs just after, it would see
      that the 'BUSY' flag is set then understand that R2 has just completed,
      which is wrong!
      
      So the state of 'BUSY' flag is not a proper way to detect and handle
      crypto request completion.
      
      This patch fixes this race condition by using two different tasklets, one
      to handle the crypto request completion events, the other to manage the
      crypto queue if needed.

      crypto: atmel-sha - fix crash when computing digest on empty message · 1900c583
      Cyrille Pitchen authored
      
      
      This patch fixes a crash which occured during the computation of the
      digest of an empty message.
      
      Indeed, when processing an empty message, the atmel_sha_handle_queue()
      function was never called, hence the dd->req pointer remained
      uninitialized.
      
      Later, when the atmel_sha_final_req() function was called, it used
      to crash while using this uninitialized dd->req pointer.
      
      Hence this patch adds missing initializations of dd->req before calls of
      the atmel_sha_final_req() function.
      
      This bug prevented us from passing the tcrypt test suite on SHA algo.

      crypto: ccp - Add hash state import and export support · 952bce97
      Tom Lendacky authored
      Commit 8996eafd
      
       ("crypto: ahash - ensure statesize is non-zero")
      added a check to prevent ahash algorithms from successfully registering
      if the import and export functions were not implemented. This prevents
      an oops in the hash_accept function of algif_hash. This commit causes
      the ccp-crypto module SHA support and AES CMAC support from successfully
      registering and causing the ccp-crypto module load to fail because the
      ahash import and export functions are not implemented.
      
      Update the CCP Crypto API support to provide import and export support
      for ahash algorithms.

      And right he is!  The Authenticode specification is a paragon amongst
      technical documents, and has this pearl of wisdom to offer:
      
      ---------------------------------
      Authenticode-Specific SignerInfo UnauthenticatedAttributes Structures
      
        The following Authenticode-specific data structures are present in
        SignerInfo authenticated attributes.
      
        SpcSpOpusInfo
        SpcSpOpusInfo is identified by SPC_SP_OPUS_INFO_OBJID
        (1.3.6.1.4.1.311.2.1.12) and is defined as follows:
        SpcSpOpusInfo ::= SEQUENCE {
          programName  [0] EXPLICIT SpcString OPTIONAL,
          moreInfo     [1] EXPLICIT SpcLink OPTIONAL,
        } --#public--
      
        SpcSpOpusInfo has two fields:
          programName
            This field contains the program description:
            If publisher chooses not to specify a description, the SpcString
            structure contains a zero-length program name.
            If the publisher chooses to specify a
            description, the SpcString structure contains a Unicode string.
          moreInfo
            This field is set to an SPCLink structure that contains a URL for
            a Web site with more information about the signer. The URL is an
            ASCII string.
      ---------------------------------
      
      Which is to say that this is an optional *unauthenticated* field which
      may be present in the Authenticated Attribute list.  This is not how
      pkcs7 is supposed to work, so when David implemented this, he didn't
      appreciate the subtlety the original spec author was working with, and
      missed the part of the sublime prose that says this Authenticated
      Attribute is an Unauthenticated Attribute.  As a result, the code in
      question simply takes as given that the Authenticated Attributes should
      be authenticated.
      
      But this one should not, individually.  Because it says it's not
      authenticated.
      
      It still has to hash right so the TBS digest is correct.  So it is both
      authenticated and unauthenticated, all at once.  Truly, a wonder of
      technical accomplishment.
      
      Additionally, pesign's implementation has always attempted to be
      compatible with the signatures emitted from contemporary versions of
      Microsoft's signtool.exe.  During the initial implementation, Microsoft
      signatures always produced the same values for SpcSpOpusInfo -
      {U"Microsoft Windows", "http://www.microsoft.com"} - without regard to
      who the signer was.
      
      Sometime between Windows 8 and Windows 8.1 they stopped including the
      field in their signatures altogether, and as such pesign stopped
      producing them in commits c0c4da6 and d79cb0c, sometime around June of
      2012.  The theory here is that anything that breaks with
      pesign signatures would also be breaking with signtool.exe sigs as well,
      and that'll be a more noticed problem for firmwares parsing it, so it'll
      get fixed.  The fact that we've done exactly this bug in Linux code is
      first class, grade A irony.
      
      So anyway, we should not be checking this field for presence or any
      particular value: if the field exists, it should be at the right place,
      but aside from that, as long as the hash matches the field is good.

      crypto: caam - make write transactions bufferable on PPC platforms · e7a7104e
      Horia Geant? authored
      Previous change (see "Fixes" tag) to the MCFGR register
      clears AWCACHE[0] ("bufferable" AXI3 attribute) (which is "1" at POR).
      
      This makes all writes non-bufferable, causing a ~ 5% performance drop
      for PPC-based platforms.
      
      Rework previous change such that MCFGR[AWCACHE]=4'b0011
      (bufferable + cacheable) for all platforms.
      Note: For ARM-based platforms, AWCACHE[0] is ignored
      by the interconnect IP.

      vmstat: Remove BUG_ON from vmstat_update · 587198ba
      Christoph Lameter authored
      If we detect that there is nothing to do just set the flag and do not
      check if it was already set before.  Races really do not matter.  If the
      flag is set by any code then the shepherd will start dealing with the
      situation and reenable the vmstat workers when necessary again.
      
      Since commit 0eb77e98
      
       ("vmstat: make vmstat_updater deferrable again
      and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
      a particular cpu to be handled by vmstat_shepherd.  This might trigger a
      VM_BUG_ON in vmstat_update because the work item might have been
      sleeping during the idle period and see the cpu_stat_off updated after
      the wake up.  The VM_BUG_ON is therefore misleading and no more
      appropriate.  Moreover it doesn't really suite any protection from real
      bugs because vmstat_shepherd will simply reschedule the vmstat_work
      anytime it sees a particular cpu set or vmstat_update would do the same
      from the worker context directly.  Even when the two would race the
      result wouldn't be incorrect as the counters update is fully idempotent.
